Uninsured motorist coverage rules in South Carolina

If the driver who hit you had no insurance, too little of it, or drove off before you got a plate number, your own policy is often what stands between you and the medical bills. South Carolina builds specific rules around that coverage, and they aren't the same as the general concepts a national guide describes. This page sticks to what actually controls a claim here: the required limits, the coverage your insurer only has to offer, and the conditions that decide whether you collect.

What the state requires you to carry

Every auto policy issued in South Carolina has to include uninsured motorist (UM) coverage. It isn't optional. Section 38-77-150 says no policy "may be issued or delivered" unless it contains a UM provision that pays you "all sums which he is legally entitled to recover as damages from the owner or operator of an uninsured motor vehicle."¹

The floor matches the state's minimum liability limits: $25,000 for bodily injury to one person, $50,000 per accident when more than one person is hurt, and $25,000 for property damage, written as 25/50/25.² Because the UM statute pegs its minimum to those numbers, your mandatory UM coverage sits at 25/50/25 too, and it covers property damage as well as injuries, unless you buy more.¹²

So if an uninsured driver injures you, you already carry at least $25,000 on your own policy to turn to. A lot of people never realize it's there.

UM, UIM, and the form your insurer must hand you

South Carolina treats uninsured and underinsured coverage as two different things, and the difference matters.

Underinsured motorist (UIM) coverage is not mandatory. Section 38-77-160 requires insurers to offer it, up to the limits of your own liability coverage, "to provide coverage in the event that damages are sustained in excess of the liability limits carried by an at-fault insured or underinsured motorist."³ In plain terms, UIM is what you reach for when the other driver had insurance but not enough to cover what they did. You can decline it, but the insurer has to give you a genuine chance to buy it.

That offer isn't a formality. Section 38-77-350 requires the Department of Insurance to approve a standard form insurers use to offer optional coverages, with a space to accept or reject and a space for your signature.⁴ The real teeth are in the default rule. If you never return a signed offer form within thirty days, the insurer "shall add on uninsured motorist and underinsured motorist coverages with the same policy limits as the insured's liability limits."⁴ A rejection has to be a real, signed rejection. Doing nothing gets you more coverage, not less.

When the other driver is underinsured

How do you know the at-fault driver counts as underinsured? Section 38-77-160 frames it around limits: UIM steps in when your damages run past the liability coverage the at-fault driver carried.³ Say a driver with a 25/50 policy causes $80,000 in harm and you carry $100,000 in UIM. Their insurer pays toward its limit, and your UIM is there to reach beyond it. The exact interplay between their payment and your UIM limit is policy-specific, so confirm your numbers, and tell your own insurer, before you accept and release the at-fault driver's payment.

Stacking across your vehicles

If you insure more than one car, whether you can combine, or "stack," this coverage is governed by Section 38-77-160, and the statute reads more like a limit than a green light. Where an insured is protected by uninsured or underinsured coverage above the basic limits, "the policy shall provide that the insured or named insured is protected only to the extent of the coverage he has on the vehicle involved in the accident."³ Whether stacking helps you depends on your specific policies and the car you were in, and the cases interpreting this language draw fine distinctions. Have someone read your declarations pages before you assume a number.

Hit-and-run and phantom drivers

A driver who causes a wreck and disappears is treated as uninsured, so your UM coverage can respond. South Carolina puts conditions on those "John Doe" claims, though, and missing one can sink the case. Under Section 38-77-170, if the at-fault driver is unknown, there's no recovery under your UM coverage unless:⁵

• you or someone on your behalf reports the accident to an appropriate police authority within a reasonable time, and
• one of three things is true: the unknown vehicle physically contacted you, someone other than you witnessed the accident, or you can produce a recording of it, and
• you weren't negligent in failing to get the other driver's identity at the scene.⁵

The physical-contact requirement is the one that catches people. If a car runs you off the road and never touches you, and no independent witness or recording exists, the claim can fail even when the other driver was plainly at fault.⁵ Get a police report started and look for witnesses or dashcam footage before you leave.

No PIP, and who you actually file against

South Carolina is an at-fault state and does not run a no-fault system.⁶ Section 38-77-144 says flatly that "there is no personal injury protection (PIP) coverage mandated under the automobile insurance laws of this State."⁷ There's no PIP filing deadline to track, because there is no PIP. Medical payments coverage exists, but only as an optional add-on.

A UM or UIM claim is unusual in one respect: you're collecting from your own insurer. That doesn't make it friendly. Your carrier can step into the shoes of the absent or underinsured driver and dispute both fault and the value of your injuries. South Carolina uses modified comparative negligence, so you can recover only if you're 50 percent or less at fault, and your award is reduced by your share of the blame. That rule comes from the state Supreme Court's decision in Nelson v. Concrete Supply Co.⁸

The deadline

You generally have three years from the date of the crash to sue. Section 15-3-530 sets that window for personal injury, and it runs from the date of injury.⁹ The clock can pause while an injured person is a minor or under a legal disability, but don't build a strategy around that. Your own policy may also impose shorter notice requirements for UM and UIM claims, so read it early rather than after a deadline has passed.

Property damage follows the same three-year limit under the same statute.⁹ If your car lost market value even after a proper repair, that's a separate claim; see our guide to diminished value in South Carolina.

Getting the report and the right help

The official crash report is the document your insurer and any attorney will want first. Our South Carolina crash reports page covers how to get it.

These claims turn technical fast, especially the stacking questions and the John Doe conditions. If an insurer is low-balling a UM or UIM claim, or denying one on a physical-contact argument, it's worth talking to a South Carolina attorney. You can start with the legal directory.
